wherein: j Figure 1 1s a view partly in side elevation and partly insection, showing my mprove ment. Fig. 2 is a section taken through thetop of the casing and showing the form ofand the means for securing thehousing for "the indicator; Fig. 3 1:; a section on line 3 3 6f Fi 1;and Fig.4 is a section on line t-4 ot 'Fig, 1. i

,,Referri11g to the drawing, A represents the main member 'of 'alnietercasingof any usual form.

B is a registering mechanism or indicator. from which readings aretaken; this mechanism or indicator being also of any usual form andprojecting throu h or being visible through the upper-end the maincasing member. Y

O, is a glass dome-shaped housing mounted upon themember A andinclosingthc registering mechanism or indicator. The member C issecllretliirplace by an *air-tight connection so that all dirt or gritare exeluded,v thereby enabling the registering mechanism' to operateaccurately and reliably. The joint is preferably made as folions:Theupperface ofthe member A. is provided with an annular recess orgroove a surrounding the open ng a. and the dome or housing has anannular flange 0 at its lower edge 'ada ted to enter intov the recess orgroove. seal D of some lnnd is "prefer ably farranged between the domeand the main casing r'neniberi this seahbeingiin tlfd form of a comressib e gasket; or, if desired, comprising a ayer of cement WlllClLWlllnot only act-as asealln'g means butwlll ald 1n 4 s ecuring the dome inplace.

Where. the upperend of the. main casing member terminates in a liange,'as at o The topof the member C is prefer I shapedso as to term a convex lens, as at cWhen the dials or other indicating devices o'f tlie'meter are viewedthrough this lens- \COIlllGCtOd improperleach other. This in.

like. top of the housing, they appear in ma very easily and withoutdanger of error.

Inorder to prevent the incter from being so as to cause the fluid." toflow'theret1rough'in the reverse direction from that'intendcd, I makethe inlet andoutlet connections difl'erent. from be accomplished invarious ways,,of co'ur. e: a'sim plearrangement consisting in formingthe inlet ['9 tion, E, of the casing with sci'ewthrea s e as; isnowcustomary, thereby ermitting the inlet pi e F5 to be'connecte to themeter by a simple unionjG; "and providing the v pair of gear wheelsthrough and through a similar flange z on the PIPE.

Accidental reversal of the'meter connections will of course be avoidedby making the inlet and outlet connections different from eachother-abut, in order .to insure against a lowering of thetotalsindicated by the re" istering mechanism when the meter is wil ullyreversed, I prefer to arrange the drivin connection between the motormemher 0 the meter and the member which gives the reading in such amanner that the latter member will always be driven inthe same directionregardless of the direction .in which the motor works. I In thearrangement shown in the drawing, L represents ashaft for driving theclockworks or other parts constituting the regis tering and indicatingmechanism, and M is an arm or finger extending from any desired isuitatil supported within the meter-1n any suitabl manner, the shaft 'Lpro'ecting downwlafi'dly through the upper 0- these plates 1 O is ashaft naledwitihin t e lower" late rpjectingthrougl; and jour- At thelower endof this latter s aft is an arm 0 which is a apted to beengagedin the usualway by the otor memberM so as to cause the shaft 0{ii be rotated, step by step, when fluid is passing through the meter..Bei tween the sha ts L and O, I place two sepa rate trains of caring soarranged that they tend to rotate he shaft Liin op osite directions uponrota ion of the shaft are provided s that" only one train at a Clutchestime can follow \its tendency, these clutches I rendering one trapn oerative when the shaft. e f rectlon' and bringing itrain-Ewhen theshaftre- O revolves in .0 into play the othe volves in the op will be seenthat t 1e rotate in one directi site direction.

It will thus be seen that there are two trains of gearsbetween the shafts L and O: one comprising the gear wheels Z, j), 21 and0.: and the other comprising the gear wheels Z, r, r, g, g and 0. Itwill be seen that by this arrangement a rotation of the driving shaftwill result in a rotation of neetion is completed; and therefore by providing suitable clutches, a rotation of the driving shaft in eitherdirectioncan be transformed into a rotation of the driven shaft in asingle direction. It will also be seen that the number of elements inthe gear trains may be varied within any desired limits as long as oneless element is contained in one train than in the other.

The clutches may, of course take any suitable form in so far as thebroader aspects of my invention are concerned; but I prefer to use anarrangementwhich is free from springs and which will operate positivelyinany position in which a meter may be placed. It is best to avoidsprings since they will be corroded by the moisture in the meter andwill .then be unableto perform their functions properly. It is also ofad vantage to have clutches which will not be att'ected by tilting themeters or turning them upside down. In the preferred ari-aiigeiiieiitwhich 1 have. illustrated, the wheels p and are made loose on theirshafts, and fi'xcd to the shaft directly above them' are ratchet-wheels,S and S respectively.

T and T are pawls carried respectively upon the gear wheels I and inposition to engage with the ad acent ratchet wheels. The pawls andratchets in the two trains are of course reversely arranged so that whenthe driving shaft is traveling in either, direction and one pawl andratchet is operative' the other is idle. The pawls and ratchets arepreferably made like esci'ipeinents so that each pawl will be forcedpositivcly into engagement with one of the teeth of its ratchetwlieclwhen it is carried in the proper direction by its supporting gear wheel.

Referring tol ig. 4, it will be seen. that a rotation of the sha t'ttOwhich-causes the gear direction will result: in causing gear wheel 7) tobe clutched to shaft 1? tlirouglrtl'ie nose :5 on one end of the pawl'l. and one of the teeth of ratchet wheel S, At the. same tiin thecorresponding and t of the pawl T will v leaving the gear wheelq free torevolve UpOnJth shaft and rendering that train noperative. It wiltbeseen'that as the nose t rises along one of the teeth of theratchet WheelS, the op ositc endof the pawhif will be depressef 'Will ride idlyoverits coi'iperating ratchet wheel and the train which was previouslyactive will now be idle. the action of the clutching mechanism ispositive and not affected by, the position which' the meter may beoccupying. vIf desired the two trains may be arranged so that they .Willdrive the registering or indicator mechanism at different rates ofspeedfor 'a given speed of the drivng' shaft-, -Therefor e, when the meter isproperlyconnected, it will register proper-1y; while, upon reversing theconnection, the meter will registerioo rapidly, causing a loss to theconsumer instead of to the vender.
